How do I find the task state?Posted by Ricky on March 4, 2008 Given a task handle, I need to find the state of a task; either Ready, Blocked, or Suspended. How do I do that? I don't see a function for that.

FreeRTOS doesn't provide such a function. > How do I do that? Keep tracking of what you're programming. If the task is executed it is in ready/run state. If you call vTaskDelay() it switches to blocked state for number of ticks. If you call vTaskSuspend() the task is in state suspended. RE: How do I find the task state?Posted by Richard on March 4, 2008 You could implement such a function but it would not be particularly quick. The list from which a task is referenced denotes the tasks state, and as references are bidirectional it is straightforward to find the list. Look at the function vTaskList() for some clues - this prints out information on each task, including the state of the task. Regards. RE: How do I find the task state?Posted by Ricky on March 4, 2008 All of the lists are static. I can't access them from outside of the tasks.c module. Is there a global way to access the lists? RE: How do I find the task state?Posted by Richard on March 4, 2008 There is no global way of accessing the lists - that is intentional. You can add functions to tasks.c to access the lists. Regards.
